CUTTING-MACHINE', FOR B ULES AND SLUGS.

To all whom it may conce-m citizen of -thc United States, residing at Brooklyn, county of Kings, State of New` 5 `Yorkhav'e'invented certain 'new and useful Improvements in Cutting-Machines for Rules and Sluos, of which the followingis a full, clear, an exact description. f

M v invention relates to an improved apparatus for cutting rules, slugs and the like, such as used b v printers, the object being to provide a simple and effective means for ac-,n-

\ complishing this purpose, which means may be readily manipulated and th'e slugs and' V rulesmay becut olf square or beveled andV v may likewise be milled or smootliedzup at the ends.

of the complete machine on a reduced scale. A Fig. 2 is a vfront eleva-tion thereof. Fig.`3 is a relatively.enlarged detail plan view of a part of a mechanism as it would appear in operation. Figs. 4, 5 and G are riewsjof iletails.

1 is a-suppoiting1'aine. 2 is a table carried thereby, upon which the work is placed. 3 is a. back pia'oted at LLat one side of the table. f

is alateh by which the back 3 may he held in different positions, that is Ato say,

the .position shown .in Fig. 1, wherein the' rules or slugs are to be en( oli' square, or the dotted position indicated in Fig. 3. where the rules or slugs are to be beveled', this latch 35 being of the plunger type and cooperating with sockets, as 2, in `the table 2J 6 represents a bunch of slugs in place on the table 2 and held against the back 3 readyl to be cut and trimmed at the ends. 40 holding means comprises a ratchet Slide 7 provide'duvith a 1`v:ullil{e l1amlle 8 :xt ,the front end, which permits thc slide 7 to be Aushed ahead. ln thefront end of the slidf` is a sjiring-pressed plunger 9, which en- 45 gages directly ith the slug or bunch of slugs 6. The ratchet is liest seen in Fig. 4, wherein the ratchet teeth 10-10 are shown on the lower side of theplunger 7, with an appropriate pawl 11 arranged adjacent thereto.

12 is a guide for the slide 7, said guide being provided `with a springpressed stud 13 designed to yieldingly hold the rod 7 down against the ratchet 11. As the rod 7 1s pushed ahead, the teeth slip over the Specification of Letters Patent.

slug, or bunch`of slugs, and puts the spring 9a under compression. VThe'slide 7 is retained'in this position by the .pa-wl 11.

When the slug or slugs are held in placeby 6l) theplnger 9 underthe act-ionof -spr'i'ri'g' the ends of the slu r or slugs project beyond the edge ofV the table to the desired degree to be cut off and trimmed by a cutter 14.

" By preferenre I provide-mechanical means l for moving thegtable, although this is notes# 30 sential in all cases. Onesimple form of mechanical means for mov-ing the table in a. direction to cnt theslugs is illustrated inthe drawings,V said uneans comprising aspur gear 19 on the'shaft 1G meshingwiththe 35 i latter carries a vinion-22 meshing within. rack 23 on the unc erside of the table 2.
